Aluminium foil blanks yog txias dov aluminium coils nrog lub thickness ntawm 0.4-0.7mm thiab tus nqi siab ntawm ntau yam deformation. Aluminium ntawv ci blanks yog thawj zaug pre-quenched ntawm 240-480 degree thiab tom qab ntawd muab tso rau hauv ib lub yob xovxwm, qhov uas lawv tau dov rau hauv cov ntawv los ntawm roughing, nruab nrab thiab tiav nrog steel yob uas muaj ib tug siab hardness thiab high degree ntawm tiav, thiab tom qab ntawd thaum kawg quenched los ua cov ntawv txhuas. Kev tswj ntawm aluminium foil thickness tuaj yeem ua tiav los ntawm kev kho qhov nro, dov quab yuam nyob rau hauv ntxhib dov thiab ceev hauv xov dov.
Hauv kev ua tiav, lub thickness ntawm cov ntawv ci txo qis thaum dov ceev nce; qhov siab dua qhov nro, qhov qis dua lub thickness. Qhov tsawg kawg nkaus thickness uas tsim los ntawm txoj kev sawb ntau lawm tuaj yeem ncav cuag 0.0025mm, qhov dav tuaj yeem mus txog 1800mm. Qhov no aluminium ntawv ci yam tsis muaj lwm yam kev ua yog hu ua lub teeb ci los yog cov ntawv ci dawb, lub teeb ci muaj peev xwm tsis zoo, tsis tshua siv ib leeg, feem ntau raws li kev siv sib txawv, cov ntawv ci ci kom sib sib zog nqus ua, ua los ntawm cov khoom ntim ntau dua.
